st: RE: -margins- vs -adjust-

-adjust- had some nice features that -margins- seems to lack, or else maybe I just don't properly understand. For instance, -adjust- used to be able to take a variable that wasn't in the model as an argument and generate predictions, etc., for it.
Example:
Run a logit model over a continuous covariate, then run -adjust- over a binned version of that covariate to make a nice table of predicted probabilities.
Let me see if I can make an example:
. sysuse auto
. gen mpg2 = 10*trunc(mpg/10)+5
. logit foreign mpg
. adjust, by(mpg2) pr ci vertical
Which gives:
Dependent variable: foreign Command: logit
Variable left as is: mpg
mpg2 pr lb ub
15 .152759 [.074742 .286956]
25 .353318 [.238384 .488149]
35 .692834 [.411283 .879263]
45 .89765 [.545156 .984657]
Key: pr = Probability
[lb , ub] = [95% Confidence Interval]
In short, one of the things I liked about -adjust- was the fact that it was a little bit "hackable." :) I simply haven't had to do any kind of serious analysis using Stata 11 recently (too much other BS to deal with, committees, etc., plus the fact that some RL things intervened) so maybe there is a way and I'm simply not seeing it.
